A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

A big update to the game is planned to happen sometime soon so the name has been changed from Motor Assailant: Prologue to Motor Assailant: Betrayal, as it is going to be more than just a prologue to the 'main game'.
Our main game Motor Assailant is now available at 75% discount! https://store.steampowered.com/app/1163730/Motor_Assailant/
Our main game Motor Assailant just received the biggest update yet, it is mostly based on player feedback. Also the game is currently available at 50% discount. https://store.steampowered.com/app/1163730/Motor_Assailant/
Our main game Motor Assailant is now available at 50% discount! Also the next big update which will change vehicle physics and handling is on the way. https://store.steampowered.com/app/1163730/Motor_Assailant/
Our main title Motor Assailant is currently available at 20% discount. It features 5 different environments, 6 combat vehicles each with it's own unique weapon, giant bosses and an encounter with aliens. Get it now while the discount is available.
Car physics/game feel updated to be more in line with the main Motor Assailant game.
Rebalanced boost ability so it makes more sense to use it continuously rather than in short bursts only UI tweaks Added sound effects to some events Replaced some old sounds with new ones Added some destructible rubble to maps
Modified physics model of the player vehicle, should be a lot less bouncy and easier to maneuver now Added some degree of air control. While in air use your movement and steering controls to rotate your vehicle Enemy vehicles fire is now more precise, especially at later levels Some memory optimizations
Missiles now regenerate automatically Missile pick ups permanently increase maximum number of missiles Reduced amount of missile pickups on levels Number of missiles will not be saved on death Missiles no longer target dead enemies Main menu now has options to continue or start a new game New powerup: weapon boost
Hello everyone. Unfortunately I had to postpone the release date of Motor Assailant: Prologue by a few days. There is also good news: demo version of the main game Motor Assailant will become available shortly on the game page.
